Everything a supply house runs on

One system from the counter to the general ledger.

  • Counter sales and orders

    Scanner-fast counter sales, quotes, orders, back orders and returns.

  • Pricing

    Contract, matrix and job pricing, with every net price explained.

  • Inventory

    On hand, committed and on order for every warehouse and bin.

  • Purchasing

    Purchase orders and receiving, with back orders released as stock lands.

  • Warehouse and delivery

    Pick, pack, stage and deliver, with proof of delivery at every stop.

  • Full accounting

    General ledger, receivables, payables and bank, posted as you work.

Switch without starting over

Bring your codes, prices, balances and history. Every number ties out before you go live.

  1. 1

    Export

    The files your system already gives you: exports, reports or spreadsheets.

  2. 2

    Map

    A ready-made profile reads DDI Inform; import templates cover any other system.

  3. 3

    Rehearse

    Load into a private sandbox, reset it and load again as often as you need.

  4. 4

    Tie out

    One report checks every count and balance against the old system before you sign off.

  5. 5

    Go live

    Cut over at a month end with a runbook, keeping your codes and history.
