The verdict in three sentences
A contractor tracking 450 bid bonds, performance and payment bonds, standby letters of credit and retainage items in spreadsheets almost always pays fees on instruments that should already be released. A bond and guarantee tracking web app costs, as a 2026 order of magnitude, 50,000 to 90,000 USD and ships in four months. With standby letters of credit priced at 0.5 to 1.5 % a year, chasing releases on time is enough to save around 140,000 USD a year for a mid-sized portfolio.
Why spreadsheets drain treasury
A heavy civil or general contractor in the New York metro area with around 350 million USD in revenue typically carries surety bonds from two or three sureties plus standby letters of credit from several banks, often above 90 million USD outstanding. Public owners such as city and state agencies require bid, performance and payment bonds; private owners and lenders often ask for letters of credit; retainage of 5 to 10 % is withheld on progress payments until completion.
The problem is the end of life. A letter of credit keeps accruing fees until it is formally cancelled. Retainage stays with the owner until someone files the closeout paperwork. Bonded capacity stays consumed until the surety confirms exoneration. In a shared 450-row spreadsheet across treasury, project managers and legal, 10 to 20 % of exposure is routinely dormant.
Consumed surety capacity and LC lines also limit your ability to bid on new work, a real opportunity cost.
What the app does
| Function | Detail | Benefit |
|---|---|---|
| Single instrument register | Type, project, beneficiary, surety or bank, amount, dates, status | No more spreadsheet versions |
| Milestone calendar | Substantial completion, warranty end, release deadline | No forgotten instruments |
| Automatic alerts | Email at 60 days, 30 days and day after deadline to PM and treasury | Releases chased on time |
| Release and closeout letters | Templates for owner, surety and bank | 15 minutes instead of an hour per file |
| Capacity tracking | Exposure per surety and bank, fee rates, available capacity | Better allocation and negotiation |
| Fee reconciliation | Billed fees compared with actual exposure | Catches undue charges |
| CFO reporting | Exposure, annual cost, dormant items, retainage receivable | Monthly control |
The app connects to your project management or construction ERP for completion dates and to accounting for fees and retainage receivable. Access is role-based: project managers see their jobs, treasury sees everything.

Mini case study
Michael, treasurer of a heavy civil contractor in New York (350 million USD revenue), manages 35 million USD of standby letters of credit at an average 1 % a year, so 350,000 USD of annual LC fees, plus 60 million USD of surety bonds.

- Dormant LC exposure found during migration: 20 %, so 7 million USD.
- Cost of that exposure: 7 million × 1 % = 70,000 USD a year.
- Retainage collected 45 days earlier on 12 million USD at a 6 % cost of capital: about 89,000 USD a year.
- Conservative combined saving retained: 140,000 USD a year.
- Project cost: 75,000 USD, plus 12,000 USD a year for maintenance and hosting.
Payback is under seven months, and freed bonding capacity lets the firm bid on new public work without renegotiating its surety program.
FAQ
Isn't a treasury management system enough?
Treasury systems handle cash and positions well, but their guarantee modules are often thin and cost roughly 30,000 to 70,000 USD a year in 2026. A dedicated app follows the full lifecycle, from bid to release.
How long does migrating 450 instruments take?
About 2 weeks including document checks. Expect 5 to 10 % of rows to show an amount or date inconsistency.
Is the data secure?
US hosting, encryption, single sign-on and an audit trail. Roles separate 10 treasury profiles from 40 project managers.
How does the app compute release dates?
It starts from substantial completion or final acceptance, applies the contractual warranty period and shifts the date if punch-list items remain open. An alert fires 60 days before.
What savings should we expect?
On instruments priced at 0.5 to 1.5 % a year, releasing 10 to 20 % of dormant exposure typically means 70,000 to 200,000 USD a year for a portfolio of this size. The real figure appears as soon as data is migrated.
