Bookkeeping for construction and trades

In construction, payments come in installments, costs come as materials, wages, and subcontractors, and in between there are special VAT rules. We keep the figures for each construction site in one place.

Your industry

What sets your industry apart

Construction contracts run for months and are settled through progress, partial, and final invoices. Clients hold back retentions, pay with a discount, or reduce certain line items. So that it’s clear at the end what each construction site has earned, we assign invoices, payments, and retentions to the respective contract.

Special VAT rules apply to construction services. If you provide construction services to another construction company, under certain conditions the client owes the VAT and you invoice the net amount. The tax advisor determines whether this reverse charge applies. When posting entries, we check whether your invoices are consistent with this and point out any discrepancies. Also note that for advance payments, VAT arises as soon as the payment is received.

If you receive construction services from subcontractors, you may be required to withhold a portion of the payment as construction withholding tax and remit it to the tax office, unless the subcontractor provides a valid exemption certificate. We ensure that an up-to-date certificate for each subcontractor is available in the portal and notify you when one is about to expire.

At year-end, work in progress becomes an issue: services that have already been performed but not yet invoiced. The tax advisor values them in the financial statements; we provide the tax advisor with the contracts, including costs incurred to date and progress payments.

Cash flow in the construction industry is also a matter of timing. Materials and wages are paid immediately, progress invoices only after the client has reviewed them, final invoices often weeks later, and retentions only once the warranty period has expired. With the list of open items per contract, you can see where the money is and follow up as needed. Upon request, we prepare the figures for bank meetings and guarantees.

Attention to detail

What we pay attention to

  • Contracts and construction sites: progress payments, partial invoices, and final invoices by contract
  • Retentions and cash discounts: kept open until they are paid or written off
  • Reverse charge: invoices prepared in accordance with the tax advisor’s assessment
  • Subcontractors: exemption certificates kept up to date, otherwise a note on construction withholding tax
  • Materials and equipment: purchases, rentals, and leases by construction site, where desired
  • Advance payments: VAT arises as soon as the payment is received, and we record it that way
  • Vehicles and fuel cards: consolidated invoices broken down
  • Warranty: traceable rework
  • Liquidity: outstanding progress payments and retentions per contract

Payroll

Payroll in your industry

  • Construction payroll: collectively agreed wages, hardship and travel allowances, travel time based on the collective agreement and your reports
  • SOKA-BAU: filings and contributions for the vacation fund and vocational training, if your company is covered
  • Winter employment and seasonal short-time work benefits during the inclement weather period
  • Manual workers, site foremen, and salaried staff, each with different rules
  • Immediate notification: mandatory in the construction industry no later than the start of work

Receipts

Which receipts we need

  • Outgoing invoices for contracts or construction sites
  • Invoices from subcontractors with a tax exemption certificate
  • Material invoices and delivery notes
  • Equipment and container rentals
  • Fuel card and vehicle invoices
  • Timesheets or construction logs for wages
  • Guarantee certificates and statements of account for guarantee lines of credit

Take photos of the receipts on the construction site and upload them to the client portal; include the construction site name in the description. We file exemption certificates in the portal and send reminders before they expire.

Start

How we get started

To get started, we take over your current projects along with the progress payments so far, your list of subcontractors with exemption certificates, and, if we handle construction payroll, the personnel records and SOKA-BAU information. From the first month, you’ll see outstanding progress payments and retentions for each project. We’ll work with you to request any missing exemption certificates.

With your tax advisor

We post the entries; the tax advisor decides the tax treatment

We set up the chart of accounts, record ongoing business transactions, run payroll, and prepare wage tax returns. Every month, we reconcile the accounts and pass the figures on to your tax advisor.

You hire the tax advisor directly, with your own contract and billing arrangement. If you don’t have one yet, we can put you in touch with our partner tax advisor, with whom we work closely.

Decisions on tax treatment are the tax advisor’s responsibility. We post entries so that they’re ready for the tax advisor to work with immediately.

How we work with tax advisors

The tax advisor handles the following on your behalf

  • Assessment of the reverse charge for construction services
  • Construction withholding tax and filings with the tax office
  • Valuation of work in progress and provisions in the annual financial statements
  • Advance VAT returns
  • Support during tax audits

Questions

Frequently asked questions

Do you post entries by construction site?

Yes, if you wish. Then you’ll see costs, payments, and profit for each job.

Who decides whether the reverse charge applies?

The tax advisor. We check whether the invoices are consistent with that decision and point out any discrepancies.

Do you handle construction payroll with SOKA-BAU?

Yes. We calculate pay based on the collective agreement and the hours you report, and we handle the filings if your business is covered.

What happens if a subcontractor doesn’t provide an exemption certificate?

In that case, construction withholding tax may have to be withheld. We point this out to you; the tax advisor handles the filing.

We’re behind on our bookkeeping. Can you still help?

Yes. With catch-up bookkeeping, we bring the outstanding months up to date, one job at a time.

How much does bookkeeping cost for a trade business?

We offer bookkeeping and payroll at a price on request. You’ll receive your quote after filling out a short questionnaire.
