What Is Carapace

A financial operations platform that works the way your team thinks.

The pitch
A team member that does the work.

Your team talks to it in plain English. It connects to your accounting system, your CRM, your payment processor, and your inbox. It reads contracts, processes timesheets, generates invoices, tracks receivables, monitors cash, and closes the books.

It's not a dashboard you stare at. It's a team member that does the work.

Plain English — no new software to learn. Describe what you need. Carapace does it.
Reads and writes — not just reports. Creates invoices, posts entries, schedules payments.
Connects to existing systems — QuickBooks, Xero, Sage, NetSuite, Stripe, HubSpot, Gmail.
Approval before action — nothing changes your financial records without your sign-off.
Builds repeatable workflows — teach it your process once. It runs every time.

The Billing Complexity in Professional Services

The complexity isn't any single contract — it's hundreds of contracts, each with their own terms, running simultaneously.

👥
Multiple consultants, different rates
Each resource tracked independently, rolled up per client on a single invoice.
📈
Rate changes mid-contract
Escalations, role changes, renegotiations — rate transitions happen mid-engagement.
🔀
Mixed billing structures
Hourly, retainer, milestone, and hybrid billing on the same contract, simultaneously.
📋
Caps, thresholds, discounts
Overage caps, overtime thresholds, volume discounts — all buried in contract terms.
📊
Timesheets from multiple sources
CSV uploads, direct entry, or pulled from your time tracking system — all formats.
🧾
All of it must become correct invoices
Every month, across every engagement, without errors or missed line items.

Contract Structures Carapace Handles

What the contract saysWhat Carapace does
Multiple consultants on one MSAEach person tracked independently, rolled up per client

Monthly Billing — From Timesheets to Invoices

Carapace accepts hours however they arrive.

Three ways to submit hours
📊
Spreadsheet upload — CSV or Excel with consultant, period, and hours
💬
Direct entry — "Sarah did 168 hours in May"
🔄
Time tracking pull — hours flow in automatically from your system
From a simple upload, Carapace
Computes each consultant's billing at the correct rate for that period — rate phases respected automatically
Catches retainer overage — overage computed, line item created immediately
Checks volume discount thresholds — discount applied or flagged if contract language is ambiguous
Updates the receivables schedule with actuals vs estimates
Generates invoices in your accounting system — QuickBooks, Xero, Sage, or NetSuite

Building Your Own Workflows

The contract skill you just saw was built for this billing model. Your team can build more — in plain English, not code.

"When I upload a timesheet, check each consultant's hours against their contract cap. If anyone is over, calculate the overage at their contract rate. Then check if the total exceeds the volume discount threshold. Show me the summary before generating invoices."

That becomes a repeatable workflow anyone on the team can run.
The billing knowledge that lives in one person's head becomes a process the whole team has access to.
New team members follow the same process from day one — no institutional knowledge required.
The workflow runs the same way every month — no variation, no missed steps.

Security and Your Data

ConcernHow it's handled
Where does our data live?Your own isolated environment — not shared with any other customer
Who can access it?Only your authorised users — role-based access: owner, operator, viewer
How are credentials stored?Encrypted at rest — your accounting system credentials are never visible, even to your own users
Can we control what people do?Yes — read-only roles for viewers, write access only for authorised operators
Is there an audit trail?Every action is logged — who did what, when, on which record
What about the AI — can it go rogue?It only has access to the tools you've connected. Destructive actions always require human approval
SOC 2?Yes
