The AI revenue integrity platform for GovCon finance & compliance teams
Cost-type or fixed-price, AI reads the contracts, maps the costs, and prepares every invoice and submission for your experts to review and sign. Nothing slips, everything stays current, and months of manual work become days — with far fewer errors.
The contract says one thing. The government pays on another. Everything in between — cost mapping, allowability, rate drift — lives in spreadsheets, tribal knowledge, and year-end panic.
CLINs, clauses, ceilings, payment terms — hundreds of pages that define what you're allowed to bill, and when.
Invoices the government accepts, rates that reconcile, submissions that hold up under audit — and every recoverable dollar actually recovered.
Every award, mod, cost, and rate — extracted, structured, and searchable in seconds. The foundation the rest of Mastyf runs on.
Every award, mod, CLIN, and clause — extracted, structured, and linked to the costs that flow through it. Your entire portfolio, queryable in seconds instead of buried in shared drives.

Ask anything across the platform in plain language. "Which contracts hit their ceiling this quarter?" "Show me every cost flagged under 31.205." It answers with sources, not summaries.
Cost-type, fixed-price, or mixed — billing and revenue integrity on schedule and off. Scheduled work runs on the calendar; unscheduled events are ready before they arrive.
Cost-reimbursable and T&M contracts bill on incurred costs — monthly vouchers, quarterly rate checks, the year-end incurred cost submission. The reckoning is scheduled, and Mastyf works the schedule so nothing slips.
Costs pulled, mapped to contract terms, screened for allowability, and assembled into a defensible invoice — before it goes out the door, not after it bounces back.
Provisional billing rates reconciled against actuals every quarter. Catch the drift when it's a correction, not when it's a clawback.
The incurred cost submission builds itself all year. When the deadline comes, your team reviews and signs — instead of reconstructing twelve months from scratch.
A fixed price doesn't mean cost records stop mattering — progress payments are billed on incurred costs, and every milestone needs a matching invoice, released on time. Mastyf keeps both moving.
Mastyf tracks incurred costs per contract and assembles each progress payment request on clean, mapped cost data — so billing at 80–90% of incurred costs stands up to DCMA and DCAA review, and cash keeps flowing.
Mastyf matches every delivery and acceptance to an invoice and flags anything sitting unbilled — so completed work turns into a released invoice, not forgotten revenue.
They arrive without warning, and every one of them is settled on your cost records. Mastyf keeps those records mapped and ready, so the package is assembled before the moment lands.
When a termination lands, Mastyf assembles the settlement proposal from costs already mapped and screened — the buildup is ready on day one, so you recover in full instead of scrambling.
Mastyf segregates and documents the cost of every change, so an equitable adjustment goes in with the proof attached — no delta cost left unproven, no money left on the table.
Every cost in Mastyf is structured and sourced from day one — so when a post-award audit questions your certified pricing data, the audit trail is already the answer.
No rip-and-replace. Mastyf sits on top of your existing accounting system and contract files.
Awards, mods, and rate agreements — PDFs are fine. Mastyf extracts the structure.
Connect your cost data. Mastyf proposes the mapping to contracts, pools, and bases; your team confirms it once.
Every cost checked against FAR Part 31 and your contract terms — monthly, quarterly, year-end. Exceptions surface immediately.
Mastyf assembles; your people judge. Nothing is filed or invoiced without human review and signature.
Consultants bring judgment but scale by the hour. Spreadsheets scale but carry no judgment at all. Mastyf is the third option: AI does the continuous, exhaustive checking no team can staff for — and your experts keep the decisions, the client relationships, and the signature authority. Nothing about your compliance posture is outsourced. It's amplified.
Of costs screened, every month Auditors sample. Consultants spot-check. Mastyf reads every cost against FAR Part 31 and your contract terms — nothing is skipped because nobody had time.
Back per monthly close Invoice assembly, cost mapping, and allowability review that used to eat days of expert time now arrives assembled — your team reviews and signs.
Submission-ready at fiscal year end The incurred cost submission builds itself all year. When your FYE closes, year-end is a review cycle — not a five-month reconstruction.
Your contract and cost data is your most sensitive asset. Mastyf is built for the security posture serious contract work requires — not generic SaaS.
Single-tenant deployment available. Your contract and cost data stays in an environment isolated to your organization, with U.S. data residency.
Contract and cost data is never used to train models. Encryption in transit and at rest. You can export or delete everything, any time.
Role-based access, SSO support, and a full audit log of every action — because your auditors will ask, and the answer should take seconds.
No — and it's designed not to. Mastyf does the continuous, exhaustive checking and assembly work that no team can realistically staff for. Your experts keep judgment, client relationships, and signature authority. Think of it as giving your best people a permanent, tireless analyst.
The full mix — cost-plus, T&M, and firm-fixed-price. Cost-type work gets the deepest routine workflow: allowability screening, indirect rate tracking, and incurred cost submissions. Fixed-price work is covered where it counts — terminations, REAs and claims, progress payments, and defective pricing exposure: the unscheduled moments when the government looks at your costs. Most portfolios are a mix, and Mastyf handles each contract on its own terms.
A fixed price doesn't make your cost records optional — it means the cost reckoning arrives all at once, at the worst possible moment. Terminations, REAs, progress payment reviews, and defective pricing audits are all cost-based — and they land on cost records that were never built for billing. Mastyf keeps those records screened and mapped continuously, so the package is mostly assembled before the event arrives. And if you want to graduate to cost-reimbursable primes, it's the path to passing the SF1408 accounting system review without staffing a compliance function.
No. Your contract and cost data is never used to train models — Mastyf's or anyone else's. It exists to serve your organization's screening and assembly work, nothing more.
Two ways. First, prevention: costs are screened for allowability continuously, so questioned-cost exposure shrinks before an auditor ever looks. Second, evidence: every mapping, screen, and decision is logged, so when an auditor asks "why was this cost treated this way," the answer is documented — not reconstructed.
Nothing. Mastyf sits on top of your existing accounting system and contract files. You upload contracts and connect cost data; Mastyf proposes the structure and your team confirms it once.
Days, not quarters. The heaviest lift is the initial cost mapping, which Mastyf proposes automatically for your team to confirm. Most of the value — searchable contracts, allowability screening — is live from the first upload.
