The AI revenue integrity platform for GovCon finance & compliance teams

Get paid everything you’re owed on every government contract.

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.

Between award and payment sits the messy middle.

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.

Where you start

The contract

CLINs, clauses, ceilings, payment terms — hundreds of pages that define what you're allowed to bill, and when.

The messy middle — Mastyf lives here On cost-type work
  • Allowability judged from memory of FAR Part 31
  • Provisional rates drifting from actuals, unnoticed
  • Incurred cost submissions built in a year-end sprint
On fixed-price work
  • Milestones delivered, invoices never released
  • Progress payments billed off messy cost records
On any contract
  • Terminations and REAs landing with no cost story ready
  • Certified pricing data with no audit trail behind it
And on all of it: costs mapped by hand, living in Excel, owned by one person.
Where you need to land

Clean payment

Invoices the government accepts, rates that reconcile, submissions that hold up under audit — and every recoverable dollar actually recovered.

One system of record for every contract.

Every award, mod, cost, and rate — extracted, structured, and searchable in seconds. The foundation the rest of Mastyf runs on.

Contracts database

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.

AI assistant

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.

Workflows built for every contract type.

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-type · CPFF · CPIF · T&M

Cost-type work runs on a calendar.

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.

Monthly

Invoice assembly

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.

Quarterly

Drift check

Provisional billing rates reconciled against actuals every quarter. Catch the drift when it's a correction, not when it's a clawback.

Year-end

Filing assembly

The incurred cost submission builds itself all year. When the deadline comes, your team reviews and signs — instead of reconstructing twelve months from scratch.

Fixed-price · FFP · FPIF

Fixed-price work still runs on your costs.

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.

FAR 52.232-16

Progress payment requests

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.

Billing integrity

Milestone & delivery billing

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.

The on-ramp to bigger work: winning cost-reimbursable primes means passing the SF1408 accounting system review. Mastyf gets you cost-type ready — without hiring a full compliance function.
Every contract type

Terminations, REAs, and audits hit every contract.

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.

FAR Part 49

Termination settlement proposals

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.

REAs & claims

REA & claim cost packages

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.

TINA

Defective pricing defense

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.

Up and running in days, not quarters.

No rip-and-replace. Mastyf sits on top of your existing accounting system and contract files.

01

Upload your contracts

Awards, mods, and rate agreements — PDFs are fine. Mastyf extracts the structure.

02

Map your costs

Connect your cost data. Mastyf proposes the mapping to contracts, pools, and bases; your team confirms it once.

03

AI screens continuously

Every cost checked against FAR Part 31 and your contract terms — monthly, quarterly, year-end. Exceptions surface immediately.

04

Your experts sign

Mastyf assembles; your people judge. Nothing is filed or invoiced without human review and signature.

Software checks. Humans sign.

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.

100%

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.

20+ hrs

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.

Day 1

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.

Security built to the standards your contracts demand.

Your contract and cost data is your most sensitive asset. Mastyf is built for the security posture serious contract work requires — not generic SaaS.

Deployment your way

Single-tenant deployment available. Your contract and cost data stays in an environment isolated to your organization, with U.S. data residency.

Your data stays yours

Contract and cost data is never used to train models. Encryption in transit and at rest. You can export or delete everything, any time.

Access, controlled

Role-based access, SSO support, and a full audit log of every action — because your auditors will ask, and the answer should take seconds.

Common questions.

Does Mastyf replace my compliance team or consultants?

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.

What contract types does Mastyf handle?

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.

We're mostly fixed-price — is Mastyf still worth it?

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.

Is my contract data used to train AI models?

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.

How does Mastyf help in a DCAA audit?

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.

What do we need to change in our accounting system?

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.

How long does implementation take?

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.
