QuickBooks gets you to 40 placements. Then it breaks.

By the time you've pasted timesheets, matched rate sheets, and entered line items for 80 workers, it's Thursday afternoon. Your cash flow clock started Monday and you've already lost three days.

Manual line-item entry

One wrong rate on one worker and the client disputes the whole invoice. You lose a week chasing a correction.

Overdue with no system

A polite email, a wait, another email — then it gets awkward and you stop. Invoices under $2K get written off because chasing costs more than the invoice.

Factoring every invoice

You pay 3% whether the client is a reliable net-15 payer or a notorious slow-pay. You're selling receivables you didn't need to sell.

Timesheets in. Invoices out. Cash collected.

Three stages that run without your billing coordinator touching the queue.

Step 1

Upload timesheets any way you have them

Drop a spreadsheet, connect your staffing software (Bullhorn, JobDiva, Avionté), or let workers clock in on mobile. The platform catches overtime, missing punches, and rate mismatches before a single invoice goes out.

Step 2

Invoices built and scored in minutes

Consolidated invoices group by your client's purchase order, cost center, or department. Each client gets a payer-risk score based on payment behavior across the agency network — so you know which invoices to hold and which to factor.

Step 3

Collections run without you

Overdue invoices move through a calibrated escalation ladder built for B2B relationships — friendly reminder to the accounts payable contact, then escalation, then formal demand if needed. You stay in control; the platform does the work.

Everything between the timesheet and the deposit

Purpose-built for agencies placing 20 to 500 workers a week — not adapted from general-purpose accounting software.

Bulk invoice generation

Import timesheet data in any format and get consolidated client invoices grouped by purchase order, cost center, or department — with overtime flagged and rate exceptions resolved before anything goes out.

Client payer risk scores

Every client gets a payer tier — Reliable, Watchlist, or Factor Required — based on payment history pooled across the agency network. Factor only the slow payers, not every invoice you send.

Graduated collections escalation

Calibrated for B2B relationships, not consumer debt. A friendly accounts-payable reminder on day 5 becomes a formal demand on day 45. Pause escalation for any client you're actively negotiating with.

5 Friendly accounts-payable reminder
20 Escalated to accounts-receivable manager
45 Formal demand letter
60 Commercial arbitration prep

Worker classification tracking

Per-worker, per-assignment classification for employees and independent contractors. Joint-employer tenure alerts fire before you hit state thresholds. Year-end tax summary reports generate automatically.

Built for operators running high-volume placements

Independent agencies placing 20 to 500 workers a week across light industrial, events, hospitality, logistics, and retail — where billing volume outpaced the tools years ago.

🏭

Light industrial

Production lines, assembly, warehousing. Purchase-order-matched invoices with overtime and shift differential accounted for automatically.

🎪

Events staffing

Weekend billing spikes, variable crew sizes, short-run client relationships. Batch invoices across 12 venues in one run.

🏨

Hospitality

Hotels, catering, food service. Tip adjustments, split shifts, and multiple cost centers per property handled without manual reconciliation.

📦

Logistics and warehouse

Clients in logistics are slow payers by culture. The payer-risk score tells you before you're already 45 days into a cash-flow squeeze.

🛍️

Retail and seasonal

Holiday surges, pop-up crew, multi-location retail accounts. Scale placement volume without scaling the billing team.

"We're a 4-person shop placing about 90 workers a week. By the time Tuesday invoices were out it was Thursday afternoon. The first week we ran AgencyStack we were done before lunch. The slow-payer scoring alone paid for the first month — I stopped factoring three accounts I didn't need to sell."
