Millwork & Architectural WoodworkDemo Case Study

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

Previous setup
  • • 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.
Why it failed
  • • 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. 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. 2

    Week 2 — Downgrade analysis

    Transaction-level review identifying which card types downgraded and which required data fields were missing.

  3. 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. 4

    Week 5 — Test transactions

    Live test transactions confirmed qualification per card type before any production volume moved.

  5. 5

    Week 6 — Cutover

    Cutover between billing cycles, with the previous setup kept available for rollback for one full cycle.

  6. 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

Obstacle

Underwriting wanted justification for the higher per-transaction cap.

Resolution

Two years of financials and a schedule of orders above $40,000 would typically support the increase.

Obstacle

Crating and freight were billed on a separate invoice, so they never reached the transaction record.

Resolution

Billing would be changed to carry freight and crating as line items on the same invoice, which Level 3 requires.

Obstacle

Tokens issued at deposit had to survive card reissues six months later.

Resolution

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.

Frequently asked questions

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.
