Lexware Office alternative for solo service providers: fewer layers, less rework.
Lexware Office is a comprehensive solution for bookkeeping and business organization. Sumaro concentrates on the workflow solo service providers need every day: estimate, invoice, receipt, payment and next task.
Does your daily workflow fit Sumaro, and when does it not?
Sumaro is interesting if you want a single, manageable workspace for your service invoices. Lexware Office is the better fit if you need the broader bookkeeping, banking, EÜR (German cash-basis profit statement) or payroll environment.
Sumaro is this site’s own product. This comparison is an editorial assessment, not an independent review.
Less follow-up work through one focused workflow.
Sumaro brings a solo service provider’s everyday business side together in one finance cockpit: Autopilot prepares plannable tasks, AI helps with estimates, and the briefing shows open payments, revenue gaps and reserves instead of just listing documents.
- Autopilot that prepares plannable groundwork automatically
- AI help with estimate drafts and wording
- Finance cockpit with the next sensible task
- Controlled approvals instead of blind automation
Less follow-up work after every job. More time for your business.
Sumaro brings automation, AI help and a financial overview into one workspace. You copy less from one place to another and review the items where your decision really counts.
The actual time saved depends on your workflow. That is why you can measure it during the trial: time your current monthly routine once, then run the same client case in Sumaro and compare the review steps that remain.
AI help for estimates requires an enabled AI configuration. Sumaro deliberately describes automation and AI separately.
See Autopilot and the finance cockpit →Recurring invoices
Sumaro creates due invoice drafts in advance, with service period and payment terms, for you to review.
Incoming payments
You import bank transactions as a CSV. Sumaro reconciles the imported transactions and matches unambiguous incoming payments to open invoices.
Reminders and dunning letters
The daily dunning run prepares the letters that are due. Nothing is sent until you approve it.
Receipts inbox
Receipts from the monitored mailbox are collected regularly in one place for review.
Financial bearings
Payment horizon, revenue gaps and an expected tax reserve show what matters next.
In short: Sumaro cuts the business follow-up work where it repeats every month. The Autopilot prepares plannable tasks, the AI helps with estimates, and the dashboard organizes incoming payments, open items, revenue gaps and the tax reserve. Critical steps deliberately stay reviewable, so you save time without giving up control.
Compare the workflow that costs you time every month.

Instead of duplicating invoices every month, copying over service periods and checking open items separately, Sumaro shows prepared tasks and the next decision in one workspace. Test the same client case in both systems: an estimate, an invoice, an incoming payment and one open receivable. That way you compare the actual workflow, not just feature lists.
