Millwork Deposits and Progress Billing: A Sample Scenario
A custom architectural millwork shop was losing large deposits to declines and paying non-qualified interchange on every GC card payment. Restructured limits and Level 3 data changed both.

Executive summary
This is a hypothetical example created to illustrate how this service could work for a business with these needs. It is not a description of an actual client engagement. The company is invented and every figure below is an illustrative assumption, not a measured result. Assume the following scenario. Ridgeline takes a 50% deposit on custom orders that routinely exceed $40,000, then bills the balance four to six months later when the work ships. Two things would typically be breaking. Large deposits were declining against a per-transaction cap nobody had revisited since the account opened, and every general contractor paying by commercial card was downgrading to non-qualified because the deposit posted as a single undescribed amount. An example approach would be to raise the limits through underwriting, move payment collection out of a standalone virtual terminal and into the ERP, and map the line-item fields required for Level 3.
Deposits above the old cap would clear.
Commercial card payments could qualify at Level 3 where the customer's card supports it.
Open deposits would reconcile to the ERP rather than a spreadsheet.
Card numbers would no longer be held on paper anywhere in the building.

The challenge
Large deposits declining at the cap, and every commercial card payment downgrading to non-qualified interchange.
- Deposits above $25,000 declined without a clear decline reason reaching the office manager.
- Effective rate on GC card payments ran 3.11% against a blended book average of 2.58%.
- Card numbers were written on paper order forms and kept in a drawer until the balance came due.
- Open deposits were tracked in a spreadsheet that did not reconcile to the ERP.
Why the previous setup was failing
- • Standalone virtual terminal, separate from the ERP.
- • Tiered pricing with three qualification buckets.
- • Per-transaction cap set at account opening and never revisited.
- • Deposits keyed by an office manager from a card number on a signed order form.
- • A virtual terminal cannot send Level 3 line-item data, so qualification was impossible by design.
- • Per-transaction limits were set for a much smaller business and never raised as order sizes grew.
- • Tiered pricing hid the downgrades inside a mid-qualified bucket, so nobody saw the pattern.
- • Storing card numbers on paper created PCI exposure and did not survive card reissues on long jobs.
Our assessment
- Twelve months of statements normalized to a single interchange-plus baseline.
- Transaction-level review of every declined deposit over $20,000.
- Field-by-field comparison of what the ERP held against what Level 3 requires.
- Review of how balances were collected on jobs older than 120 days.
The recommended solution
- Raise per-transaction and daily velocity limits through underwriting, supported by financials.
- Replace the virtual terminal with an ERP-integrated connector that posts against the invoice.
- Tokenize the payment method at deposit so the balance can be collected without re-keying.
- Move to interchange-plus so qualification is visible on the statement.
Implementation Process
- 1
Week 1 — Statement review
Three months of statements plus a sample invoice, normalized to a single interchange-plus baseline so every line is comparable.
- 2
Week 2 — Downgrade analysis
Transaction-level review identifying which card types downgraded and which required data fields were missing.
- 3
Weeks 3–4 — Connector and field mapping
Payment connector installed against the existing ERP; invoice fields mapped to the Level 2 and Level 3 requirements.
- 4
Week 5 — Test transactions
Live test transactions confirmed qualification per card type before any production volume moved.
- 5
Week 6 — Cutover
Cutover between billing cycles, with the previous setup kept available for rollback for one full cycle.
- 6
Weeks 7–10 — Verification
First full month compared against projection; qualification reported by card type and customer.
Technology and integrations
Integration changes
- • Payment connector installed against the existing ERP.
- • Invoice line items, freight, crating and tax mapped to Level 3 fields.
- • Purchase order and customer reference fields populated from the work order.
- • Settlement data written back to the general ledger daily.
Processing changes
- • Tiered pricing replaced with interchange-plus.
- • Per-transaction cap raised to accommodate deposits on the largest orders.
- • Card data removed from paper forms and replaced with tokens.
Obstacles and resolutions
Underwriting wanted justification for the higher per-transaction cap.
Two years of financials and a schedule of orders above $40,000 would typically support the increase.
Crating and freight were billed on a separate invoice, so they never reached the transaction record.
Billing would be changed to carry freight and crating as line items on the same invoice, which Level 3 requires.
Tokens issued at deposit had to survive card reissues six months later.
Account updater would be enabled so reissued cards refresh the stored token automatically.
Measurable results
Illustrative only — modeled at roughly 71 basis points on qualifying commercial card volume, against a blended book that had been running 3.11% on that segment.
Operational improvements
- • Balance collection stopped requiring a phone call to re-read a card number.
- • Office manager no longer keys payments into a second system.
- • Open deposit tracking moved out of the spreadsheet.
Reporting improvements
- • Qualification rate reported monthly by card type.
- • Open deposits visible against jobs in production.
- • Effective rate split between GC card payments and trade ACH.
Funding improvements
- • Deposits cleared same-day rather than being re-attempted across several days.
- • Balance collection on shipped jobs could move toward on-delivery for stored-credential customers.
Customer experience improvements
- • General contractors stopped having deposits declined at order placement.
- • Balance requests arrived as a payable invoice rather than a phone call.
Before and after
| Measure | Before | After |
|---|---|---|
| Deposit acceptance | Declines above $25,000 with no clear reason | Cleared within raised, documented limits |
| Commercial card qualification | Non-qualified on effectively all GC card volume | Level 3 where the card and data support it |
| Card storage | Numbers written on paper order forms | Tokenized, with account updater |
| Pricing | Tiered, three buckets | Interchange-plus, qualification visible |

Are these results guaranteed?+
No. This engagement is demonstration content built on realistic scenarios. Actual outcomes depend on your volume, mix, software, and current pricing — which is exactly what a review establishes.
How long did the Ridgeline Millwork Co. engagement take?+
The implementation ran across 6 phases; most comparable environments cut over in 7 to 14 business days once scope is agreed.
Do we have to change software to see similar results?+
Usually not. Most of this work happens in merchant structure, pricing, data capture, and integration configuration around software you already run.
Can we see a version of this analysis for our business?+
Yes. A payment review returns the same structure — assessment, recommendation, projected impact — against your own statements.
