Three ways to start

Pick the smallest thing that solves the real problem.

Most engagements begin with one of these three. Once something is live, we grow into whatever else you need — accounting, HR, ecommerce — without a big up-front commitment.

Three engagements, three real outcomes.

Client names anonymized on request. Numbers pulled from the actual engagements. Introductions available on request under NDA.

Multi-outlet F&B · Phnom Penh

Six cafés on one POS, one inventory, one accounting bridge.

Migrated a growing café group off spreadsheets and a mismatched cash-register setup. KPOS across six outlets, live inventory sync, ABA + KHQR at the counter, nightly export into their accountant's QuickBooks.

Retail chain · KHR/USD

KHQR at every till, inventory in sync across four stores.

Retail group with four locations needed inventory that didn't drift and payments that customers already trusted. Fixed-scope 6-week build: KPOS Retail with KHQR, ABA, ACLEDA, and multi-outlet inventory. Weekly stock variance dropped materially in the first month.

SME · Spreadsheet → billing automation

Recurring invoicing without switching accountants.

Services SME running its billing out of Google Sheets, chasing payments over Telegram. Deployed KBilling with recurring invoices, KHR/USD, ABA + KHQR checkout, and auto-reminders. Existing accountant kept their workflow — we exported to their format.
