Where it hurts
Before, after.
-
TodayI price my quotes at night, by hand, and I start from scratch every time.
With PrivateCoreYou work from composite work items: materials, labour and equipment in a single reusable line. The bare cost is computed from your own purchase prices, and the selling price follows from your own coefficient. Your price base is imported from the export you already have, not handed down by the vendor.
-
TodayThe invoice went out two months ago and I still have not dared to chase it.
With PrivateCoreUnpaid invoices surface on their own with their age. First, second and third reminders are drafted at thirty, forty-five and sixty days, each with the right tone. You read them over, send the batch in one go, and the history stays attached to the invoice.
-
TodayThe crew hours are on a notepad in the van, and I copy them out on Friday.
With PrivateCoreClocking happens on the phone, on site. Down in a basement with no signal, the entry is queued and leaves on its own once the signal is back. If the same action is repeated, it still counts once: each clocking carries its own reference.
-
TodayI find out whether a job was profitable three months after finishing it.
With PrivateCoreMaterial purchases and subcontractor progress claims are charged to the job. Against them, clocked hours are valued at the employee’s real rate. The margin planned in the quote and the margin actually achieved sit on the same screen, during the works rather than after.
4 more pains we cure
-
TodayA progress claim means a spreadsheet, and I get the deposits already paid wrong.
With PrivateCoreYou enter the progress, everything else is computed: the amount for the period, the retention, the share of the deposit to offset pro rata, and the net payable. The software refuses progress that goes backwards, a cumulative figure above the contract, or retention beyond its cap.
-
TodayRenovation, energy work, new build: my accountant patches up the VAT afterwards.
With PrivateCoreEvery line carries its rate, and the invoice is broken down by rate. On subcontracted work, the reverse charge set out in article 283-2 nonies is posted on both sides and the legal wording appears on the document: you do not charge VAT to the main contractor by mistake.
-
TodayThe council rejected my submission over a reference nobody had asked me for.
With PrivateCoreBefore anything is sent to Chorus Pro, the three required identifiers are checked: commitment number, buyer SIRET and executing-service code. If one is missing, the submission is refused at your end, with the list of what is missing, rather than rejected at the buyer’s.
-
TodayElectronic invoicing in 2026? I will look at it when the time comes.
With PrivateCoreInvoices already come out as Factur-X, with the structured data attached to the PDF, and submission to the platform is traced attempt by attempt. In the other direction, your suppliers’ invoices are read and filed as purchase invoices. The ten-year legal archive starts at issue.

The gap
What we centralise, and they do not.
-
How many subscriptions
The usual stackA quoting tool, a spreadsheet to follow the job, a clocking app, an accounting portal, a platform for public contracts: that many contracts, and that many exports to redo when a figure does not add up.
PrivateCoreOne contract and one screen. The quote becomes the job, the job takes in the hours and the purchases, the progress claim becomes the invoice: nothing changes software on the way.
-
Where your data lives
The usual stackOn the vendor's servers. Your purchase prices, your coefficients and your margins, which is to say your trade itself, are hosted with a third party.
PrivateCoreOn a machine sitting at your place. The database is yours, it is backed up at your place, and nobody else reads your coefficients.
-
Your price base
The usual stackThe library is the vendor’s, often billed separately, and your supplier terms never make it in. You price with somebody else’s figures.
PrivateCoreYou import your own base, spreadsheet or export from your current tool, and you keep control of the coefficient. The libraries shipped with the software are a starting point, not a constraint.
3 more differences
-
What happens between the quote and the invoice
The usual stackHours, material purchases and subcontracting live elsewhere. The real margin is pieced back together at the end, from memory, when it is too late to act.
PrivateCoreEverything is charged to the job as it happens. Real cost is compared with the quoted cost while the works are running, and an overrun shows up within the week.
-
Public contracts and electronic invoicing
The usual stackStructured submission and the mandated format come as an option, or in a separate platform you have to feed by hand.
PrivateCoreThe mandated format, traced submission, inbound supplier invoices and regulatory archiving live in the same tool as the quote, with no bridge to buy.
-
Artificial intelligence
The usual stackTo get a draft quote, your descriptions and your prices are shipped to an AI vendor, and sometimes used to train its model.
PrivateCoreThe model runs on your machine. The draft reuses the work items from your own library at your own prices, it invents none of them, and nothing is kept until you approve it.
FAQ
What we get asked.
Compatible with Batappli or Codial?
No native import, but CSV export is compatible. For construction price libraries (BatiPrix, BetiAcc), CSV import with automatic mapping.
Chorus Pro for public contracts?
Yes, native Chorus Pro connector (Factur-X). Automatic submission of invoices to the public portal.
Ten-year structural warranty and trade card?
Documents stored in the legal vault, accessible on the move. Alert 30 days before expiry. A secure link shareable with a principal.
Clocking my workers in on site?
Mobile app with geofencing: site start, site end, break. Hours consolidated per site and per worker, automatically into payroll.
For a solo craftsperson, isn't it too much?
No: SoloCore covers the quote, the Factur-X invoice, before/after photos, customer loyalty. You save ~€200/mo over Tolteck + Capeb + iLovePDF + Smallpdf.
Reduced VAT 10 / 5.5 per line, is it in the quote?
Yes. Each line has its VAT rate (renovation / energy improvement = 10 or 5.5 by criteria, new build = 20). Customer attestation for 5.5% auto-generated.
I do my quotes from the van, often with no signal: does it hold up?
Yes. Field work runs offline: photos, clock-ins and handover reports queue up and sync on their own when the signal returns. And the quote comes together in minutes with the work-item library: in the car park after the visit, it goes out by SMS as soon as you get coverage.
I work with subcontractors: is the VAT reverse charge handled?
Yes. Each subcontracted lot is declared on the site with its amount: invoicing switches to the reverse charge with the required legal wording, and the cost flows into the actual site spend. You see the net margin, subcontracting deducted.
