Zinit Industries Professional Services
Everything a firm buys ends up in one of two places: on a client's bill, where that client's billing guidelines decide how much of it gets paid, or in overhead, which comes out of the partners' profit. Zinit's AI agents read your largest clients' guidelines into a price ceiling for each expense category, then run the bidding and level the vendors on what each client will actually pay.
Overhead at US law firms is growing as fast as their rates

Worked example: what the largest client's guidelines cut in a year
$440k a year, at one client
Our arithmetic from the example firm's March invoice and its year of hotel nights. The per diem is GSA's fiscal year 2027 lodging rate for Washington, which moves from $192 to $295 a night through the year.
A data-hosting vendor for a litigation docket passes through six sets of hands, and the last of them sits at the client.
Owns the client, the matter and the call on which vendor works on it
Gets from Zinit A vendor panel already priced under that client's guidelines, so whichever vendor the partner picks clears the client's rule on price.
Owns the review platform, the hosted data and the vendors on each matter
Gets from Zinit Bids priced per GB a month, with the cost of moving existing data shown beside each one.
Owns the vendor panels, the contracts and the renewals
Gets from Zinit A price ceiling for each category from every major client's guidelines, competing bids against it, and a leveled table.
Owns the pre-bill review, the e-billing submissions and realization
Gets from Zinit Expense lines that clear each client's rules before the invoice goes out.
Owns client confidentiality, conflicts and the security review of any vendor holding client data
Gets from Zinit Each bidder's security documents and insurance certificates with its bid, so the review starts while the vendors price.
Owns the billing guidelines and the review of every invoice
Gets from Zinit Expense lines it can pay as billed, and a new vendor put to it for approval before any of its data moves.
The guidelines live with billing and the vendor contracts live with procurement, so a price that breaks a client's rule usually surfaces for the first time as a cut on the invoice.
What Zinit doesEvery major client's guidelines read for the rules on each expense category before a vendor is chosen, with the gap shown in dollars a year.
What Zinit doesOne table of ceilings, the strictest rule among your largest clients for each category, updated when a client revises its guidelines.
What Zinit doesPanels bid against the strictest ceiling, so whichever panel vendor a partner picks already clears every major client's rule.
What Zinit doesThose renewals run as the overhead they have become, with competing publishers and vendors bidding before the renewal date.
What Zinit doesEach bidder's security documents and insurance certificates arrive with its bid, and the approval request for the client is prepared from the award.
A 103M+ supplier and company database, AI agents that read the guidelines and run the bidding, and procurement people who work beside your team.
Each major client's billing guidelines read for its rule on every expense category, such as hosting per GB, transcripts per page, copies, hotels and online research, and the strictest of them set as the ceiling the firm's vendors have to meet, each rule shown beside the clause it came from so your billing team can sign it off.
The cuts coming, by category, in dollars a year.
Competing vendors in each category, from court reporting agencies and e-discovery hosts to travel management companies, drawn from a 103M+ supplier and company database alongside the ones your team already uses, invited only after your team approves the list, and each asked for its security documents and insurance certificates with its bid.
Vendors that clear every client's rule.
The first RFP is drafted in under an hour from the guidelines and last year's invoices, the bids take the time they take, and each one is leveled on what every client will pay, what the firm would absorb, and the cost of moving work already under way.
A panel your partners can use on any client's matter.
Sometimes the incumbent re-prices under the rule and keeps the work, and then the firm stops absorbing the gap without moving anything. Zinit does not review or submit your bills, negotiate with your clients or interpret their guidelines for them, and your team directs and approves every award.
Click a step. Zinit reads your clients' billing guidelines, your e-billing adjustments and your vendor invoices. Every figure belongs to the example firm.

Five clients' rules, and the ceiling they set
| Category | A | B | C | D | E | Ceiling |
|---|---|---|---|---|---|---|
| Data hosting, per GB a month | $10 | $12 | $8 | at cost | $10 | $8 |
| Deposition transcripts, per page | $4.50 | at cost | $4.25 | $4.75 | at cost | $4.25 |
| Copying, per page | $0.10 | $0.10 | $0.15 | $0.12 | at cost | $0.10 |
| Hotels, per night | per diem | per diem | at cost | $350 | per diem | per diem |
| Online research | not paid | not paid | not paid | at cost | not paid | not paid |
Client C's $8 sets the hosting ceiling, and the federal per diem sets the hotel ceiling, since it is lower than Client D's $350 every month of the year. Client A is the largest client, the one whose March invoice is above. Online research is overhead under four of the five.
The firm's prices against the ceilings, a year at Client A
| Category | Firm pays | Client A's rule | A year at Client A | Cut a year |
|---|---|---|---|---|
| Data hosting | $16 | $10 | 4,200 GB a month | $302,400 |
| Hotels, Washington | $309 to $389 | per diem, $192 to $295 | 310 nights | $33,210 |
| Copying | $0.14 | $0.10 | 374,400 pages | $14,976 |
| Online research | $7,420 | not paid | 12 months | $89,040 |
| Deposition transcripts | $4.10 | $4.50 | 25,680 pages | $0 |
Hotels by season: the firm's negotiated rate against GSA's fiscal year 2027 lodging per diem for Washington
| Months | Nights | Firm's rate | Per diem | Above |
|---|---|---|---|---|
| November to February | 98 | $329 | $203 | $12,348 |
| March to June | 104 | $389 | $295 | $9,776 |
| July and August | 46 | $309 | $192 | $5,382 |
| September and October | 62 | $379 | $287 | $5,704 |
Transcripts already clear every client's rule, at $4.10 a page against Client C's $4.25, so they cost the firm nothing.
What a year of cuts costs at Client A
| Line | Basis | A year |
|---|---|---|
| Data hosting | 4,200 GB × ($16 − $10) × 12 = $302,400 | $302,400 |
| Hotels | $12,348 + $9,776 + $5,382 + $5,704 = $33,210 | $33,210 |
| Copying | 374,400 pages × ($0.14 − $0.10) = $14,976 | $14,976 |
| Online research | $7,420 × 12 = $89,040 | $89,040 |
Below each ceiling, a lower vendor price is the client's saving rather than the firm's, because a disbursement is billed at what the firm pays.
Three bids for data hosting, leveled on what Client A pays and what the firm absorbs
Six hosting vendors invited after your team approved the list, and three bid, each pricing 4,200 GB a month and the move of the data already hosted.
| Bid AIncumbent, re-priced in place | Bid BAlternative from your own list | Bid CAlternative added by Zinit | |
|---|---|---|---|
| Hosting, per GB a month | $9.75 | $9.25 | $7.40 |

| Under the $8 ceiling | no | no | yes |
| The 4,200 GB already hosted | stays, re-priced | moved at $12 a GB | moved at $11 a GB |

Bid AIncumbent, re-priced in place
Bid BAlternative from your own list
Bid CAlternative added by Zinit
Moving data already hosted is the firm's own decision, so no client pays for it, which is why it counts as absorbed. At Client A all three bids end the cut, and the difference between them is the client's saving.
Split the award, then the line that decides it now
Bid C is the only price under every client's ceiling, so new matters go to it from April 1, after litigation support has run it on one matter. The 4,200 GB already hosted stays with the incumbent at $9.75 until those matters close, since moving it would cost $46,200 that no client pays.
With hosting settled, the largest cut left is research, $89,040 a year at Client A, which no vendor price can make billable because four of the five largest clients will not pay for it at all. Its contract renews on the publisher's terms, so the renewal itself is the next event.
Two more events follow: the Washington hotel program, priced at or under each season's per diem, and copying. Every figure here is the example's own, and your clients' guidelines decide.
A law firm answers to its clients' guidelines, an accounting firm to independence rules, a consulting firm to its contracts and, on federal work, to the per diem. Pick the kind of firm you buy for.
Who decides: The relationship partner chooses the vendor for each matter, with litigation support, procurement, billing and the general counsel's office, and the client's legal operations team reviews every invoice.
What sets the rule
Where sourcing moves it
Panels for hosting, court reporting, copying and travel priced under the strictest client's rule, and the research renewal run as the overhead it has become.
Who decides: The chief operating officer and chief financial officer, office managing partners and the independence team, with procurement running the events.
What sets the rule
Where sourcing moves it
Bidder lists checked against your restricted-entity list before invitations go out, and events timed around the filing season so no change of vendor lands in it.
Who decides: The engagement partner and delivery lead, subcontracts and procurement, finance, and the client's own procurement team.
What sets the rule
Where sourcing moves it
Hotel programs bid at or under the per diem for the client cities and seasons you travel to, and subcontractor rates bid before a proposal fixes them.
Who decides: The principal in charge and the project manager, contracts and procurement, with subconsultants named on the team before the proposal goes in.
What sets the rule
Where sourcing moves it
Subconsultant teams bid before the statement of qualifications is due, and overhead purchases sourced with the FAR cost principles in view, since a cost the FAR makes unallowable cannot sit in the audited rate.
Every rule here comes from a published guideline, opinion, regulation or survey. Your clients' own guidelines and contracts decide, and your general counsel decides how they apply.
The example's hosting prices sit inside the ranges buyers and vendors report, and its hotel rule is GSA's own rate for the city and month.

Keep it, because it catches what is wrong with an invoice before the client sees it. Zinit works earlier, on the vendor price behind each expense line, so the line clears the client's rule before there is an invoice to review.
They still do. Zinit makes the panel they choose from priced under every major client's guidelines, so a partner's pick on any matter is one the client will pay for. A vendor off the panel stays the partner's call, and the leveled table shows what it would cost the firm at that client.
ABA Formal Opinion 93-379 bills a disbursement at what the firm pays, so a vendor priced under a client's rule only lowers that client's bill, and any part of a price above the rule is cut on review and absorbed by the firm. Your general counsel decides how the opinion and your engagement letters apply.
Then those matters use the client's vendor at the client's rates, and Zinit sources the vendors for every other matter, where the firm's own panel decides the price.
Zinit's AI agents run the event and Zinit's procurement people work alongside your team. Your team approves every invitation and decides the award, so policies and approvals never leave your people.
Only once your general counsel and security team have reviewed it, and where a client's guidelines ask for it, once that client has approved it. Zinit asks each invited vendor for its security documents and insurance certificates with its bid, so the review runs while the vendors price.
The billing guidelines your team gives it, and the invoice adjustments and vendor invoices by client and expense code, which is all the ceilings and the year's cut are built from. It does not need matter descriptions or documents and does not sign in to your clients' e-billing portals, and bidders see only the requirement your team approves, with no client named in it.
It still does. Each bidder is checked against your restricted-entity list before it is invited, and your independence team decides on anything that needs a ruling.
Then hotel bids are priced against GSA's per diem for the city and month, since FAR 31.205-46 allows lodging on federal work only up to it, and anything above the per diem would come out of the firm's margin.
Zinit is supplier-funded and free to buyers: only the supplier your team selects as the winner pays a commission, the losing bidders pay nothing, and nothing is owed until you award. The commission rates are published openly on our site, and because the fee is tied to the award your team makes rather than to who competes, Zinit earns the same whichever qualified supplier you choose.
It does not review or submit your bills, negotiate with your clients, interpret their guidelines for them or give legal or ethics advice, and it does not replace your e-billing tools, your conflicts system or your security review. Sometimes the incumbent re-prices under the rule and keeps the work, and that ends the cut just as well.
Bring that client's billing guidelines and a year of its e-billing adjustments. Zinit reads the rules, finds the vendor prices above them and runs the event, with your team directing and approving every step.
