The problem
What AVL was working with.
Before YionStack, AVL ran the business across an accounting tool, a separate CRM, a job-management app, a shared inbox and a spreadsheet for engineer availability. Every quote needed re-keying. Every invoice needed chasing. Every reschedule meant three different systems opened side by side.
The team kept growing the workaround instead of fixing the root: more spreadsheets, more shared docs, more “has anyone heard back from…” in the group chat. The cost wasn't the software bill — it was the hours each week spent translating between systems that didn't talk.
The switch
How the move actually ran.
AVL moved across over [METRIC_TBC] working days. The accounting ledger and customer list came over first — same chart of accounts, same VAT treatment, same balances. CRM contacts and open quotes followed. Engineer schedules and job records came last, once the team was confident the rest was solid.
Nothing was rebuilt from scratch. The data each tool held became columns on the same customer record, the same job record, the same invoice. Where AVL had eight logins, they now have one.
The outcome
What changed for AVL.
- Hours saved / week

- Apps consolidated
- [METRIC_TBC]
- Stack cost / month
- [METRIC_TBC]
The visible win is the operator surface — quotes drafted from the customer's last job, chase emails ready for approval the morning after an invoice goes overdue, the engineer schedule visible to whoever picks up the phone. The quieter win is what disappeared: the translation work between systems, the “who has the latest version” questions, the monthly reconciliation between the CRM and the books.
One bill replaces the stack. One operator replaces the human glue.
