Agenda/Time reporting/Invoicing/Bookkeeping project

New project for my putative business and for my wife's current operations as a speech therapist.

Requirements

1. Easy data entry
2. Possibly, google calendar as the main data input for mobile and office usage
3. If Google Calendar used, needs good integration/export capability
4. Needs to identify separate customers/projects for later invoicing/reporting
5. Must support French language
6. Regardless of data entry/storage : must provide export to local readable files for archive/backup purposes

Nice to Have

1. Nice if invoices can be produced from the time reports/agenda
2. Invoicing must support non-VAT (speech therapist) or VAT (my business) invoicing
3. For VAT, Belgian regulations and fees must be supported
4. For invoices, sending via email/Zoomit/Paypal or other modern services should be available
5. For accounts receivables, invoice tracking and payment reconciliation is a plus.  Integration with local (Belgian) bank systems is a definite plus
6. For further bookkeeping, full accounts payable module is another bonus

 INCWO

Looks like it's a french company.  Nice feature list, recurrent payment depending on activated modules, starts at 49€ / year.  So far seems to match R1-2, R4-5, N2, possibly N4-6.  Definitely not N5 for Belgian banks but I have opened a ticket to ask this very question.  The jury's out.

GTimeReport

Free! but limited to R1-4, R6.  R5 limited support (help pages via Google Translate).  So it kind of ticks all required boxes and is free.
