Days-to-cash is the number of days between when a high-ticket service business starts incurring costs on a project and when it receives payment. For most businesses running 5 to 15 simultaneous projects, that number is 83 days — full elapsed time from first material order to last payment received. The four places it gets stuck are: no deposit at contract signing, no milestone billing during the project, late invoicing after work is complete, and no structured collection sequence after the due date. The three fastest fixes — a real upfront deposit, milestone-triggered invoices, and same-day invoice dispatch — typically cut the number from 83 days to under 30.
Here is what 83 days looks like in practice.
A commercial landscaping company signs a $120,000 seasonal contract. Crew starts week one. Materials ordered: $18,000. Payroll weeks one through four: $22,000. No deposit was collected — the client is a repeat customer, it felt awkward to ask. Week nine, the scope is complete. Owner sends the invoice that evening. Client's standard terms are net 30. Check arrives day 67 from invoice date, which is day 96 from mobilization.
The owner funded $87,000 in labor and materials before seeing a dollar. Not because the client didn't pay. Not because the job went sideways. Because the billing structure had a 96-day gap built into it by default — and nobody calculated what that gap actually costs.
At current short-term borrowing rates, carrying $87,000 for 96 days costs between $1,100 and $1,400 in real terms. That cost never appeared in the estimate. It never showed up in the job costing report. It was absorbed silently, as it always is, into the owner's working capital — or into the line of credit the owner maintains specifically to bridge the gap they never formally decided to create.
According to the Federal Reserve's Small Business Credit Survey, cash flow problems are the most frequently cited financial challenge among service businesses with fewer than 20 employees — cited more often than access to credit, revenue volatility, or cost pressures. The problem is not profitability. The problem is timing.
Days-to-cash does not balloon from a single decision. It accumulates across four distinct gaps in the billing lifecycle. Fixing one of them moves the number. Fixing all four gets you to 30.
| Leak Point | What Happens | Typical Days Lost |
|---|---|---|
| No deposit or minimal deposit | Owner funds 100% of early-stage costs — materials, mobilization, first payroll — before the client has skin in the game. | 14–30 days |
| No milestone billing | Single invoice at project completion means the owner carries the full cost of the job until the last task is done. | 20–45 days |
| Late invoicing | Invoice sent days or weeks after work is complete, because the owner was busy or the paperwork wasn't ready. Every day of delay is a day added to the collection window. | 5–21 days |
| No collections sequence | Net 30 terms with no follow-up process. Clients who miss the due date hear nothing for two weeks. Net 30 becomes net 52. | 10–22 days |
These four gaps are additive. A business with all four operating at once easily lands at 83 days. A business that closes all four lands somewhere between 22 and 35.
There are a dozen ways to improve days-to-cash. These three move the number the most, the fastest, with the least friction in the client relationship.
Fix 1: Collect a real deposit before mobilization.
A deposit is not a nicety. It is a structural tool that shifts funding responsibility from owner to client at the moment it belongs there. For a $20,000 job, a 40% deposit ($8,000) covers the first payroll cycle and most of the material order. For a $100,000 job, a 25% deposit ($25,000) changes the entire cash profile of the first six weeks.
The framing matters. “We require a deposit before scheduling” is a professional standard. Most clients, especially at the high-ticket end, expect it. The ones who push back on a deposit before a single dollar of work has started are worth noticing.
Fix 2: Build milestone invoices into the contract before signing.
Milestone billing means the invoice goes out when a defined phase is complete — not when the whole project is done. Define the milestones in the contract. Tie the invoice to the milestone, not to a date. When framing is complete, an invoice goes out. When rough-in passes inspection, an invoice goes out. The client signs off on the structure at contract, so there is no surprise and no renegotiation mid-project.
| Job Size | Recommended Structure |
|---|---|
| $15K–$30K | 40% deposit / 60% at completion |
| $30K–$100K | 30% deposit / 35% at 50% completion / 35% at final |
| $100K–$250K | 20% deposit / 25% at Phase 1 close / 25% at Phase 2 close / 20% at substantial completion / 10% at final |
| $250K+ | Negotiate monthly draw schedule based on completed scope, tied to lien waiver exchange |
Fix 3: Invoice the same day the milestone is hit.
This one sounds obvious. It is almost never done. The owner finishes the scope on a Thursday afternoon, means to send the invoice Friday morning, gets pulled onto a site call, and sends it Monday. That is three days off the payment clock — for no reason other than process. The rule is simple: milestone complete, invoice sent, same business day. Not “when the paperwork catches up.” That day.
Every day of invoicing delay is a day added to the collection window on the back end. It is also a day when the client's mental account of “money I owe this contractor” fades slightly. The fastest path to payment is a professional invoice arriving while the work is still fresh.
Sending the invoice is not the end of the billing process. It is the beginning of the collection window. A business without a structured follow-up sequence turns net 30 into net 50 by default.
The four-touch sequence that works without damaging the relationship:
The tone of each touch is professional, not hostile. The goal is the money AND the review. A collections process that feels punitive gets the money but loses the referral. A process that is consistent and documented gets both.
TIM's operations manager tracks invoice status across every active and recently closed project — flagging overdue payments before they become collection problems, generating the four-touch follow-up sequence automatically at each threshold, and tracking days-to-cash as a rolling operational metric across the business. For a business running 10 active projects at once, that is 10 billing cycles running simultaneously, each with its own status, its own due date, and its own follow-up window.
A service business with 83-day average days-to-cash and $2M in annual revenue is carrying approximately $455,000 in outstanding receivables at any given time. Cutting that to 30 days means carrying $165,000 — a reduction of $290,000 in working capital requirements, with a corresponding improvement in cash availability, line-of-credit headroom, and the owner's ability to take on larger projects without funding anxiety.
The three fixes above — deposit, milestone billing, same-day invoicing — do not require a new system, a new hire, or a renegotiation of every client relationship. They require a billing structure decision made once, written into the contract template, and executed consistently.
The businesses that operate at 30 days made that decision. The businesses at 83 days made a different one — usually the default one, the one that was never consciously made at all.
For the operational model that ties billing to project milestones automatically: see how it works. For businesses ready to build the infrastructure that closes the cash gap: see if there is a fit.
