For businesses shipping regularly, paying by card per shipment creates administrative friction and cash flow pressure. Invoice billing — where all shipments in a period are consolidated into a single monthly invoice paid on credit terms — is the standard arrangement for business shipping accounts. Understanding how to access invoice payment, what credit terms to expect and how to manage shipping costs effectively helps you run your shipping operation more smoothly.

Key Benefits

Ship now, pay in 30 days

Standard 30-day payment terms mean you ship today and pay at month-end — improving cash flow, especially for businesses with long customer payment cycles.

Single monthly invoice

All shipments consolidated into one invoice with full line-item detail — simpler accounting, easier cost allocation by department or customer.

VAT deduction

Monthly shipping invoices with Portuguese VAT (23% IVA) allow full input VAT recovery on your quarterly IVA declaration — relevant for all VAT-registered businesses.

Spend visibility

Monthly invoice statements give clear visibility of shipping spend by carrier, destination and weight — useful for budgeting and identifying cost-saving opportunities.

How Invoice Billing Works for Shipping

When you have a business shipping account (either directly with a carrier or through Cargosender), your shipments are booked against your account number rather than paid per transaction. At the end of each billing period (typically monthly), the carrier or platform issues an invoice listing all shipments, weights, destinations and charges. You pay the invoice by bank transfer (SEPA/MB) within the agreed credit terms — usually 30 days from invoice date.

  • Book shipments throughout the month against your account number.
  • Receive consolidated invoice at month-end (or agreed billing date).
  • Invoice includes: shipment date, tracking number, origin/destination, weight, service used, base rate, fuel surcharge, any extras (insurance, remote area).
  • Pay by SEPA bank transfer within credit period (Net 30 is standard).
  • Invoice includes Portuguese IVA at 23% — recoverable as input tax for VAT-registered businesses.

30-Day Credit Terms — How to Qualify

Credit terms are not automatic — carriers assess creditworthiness before extending Net 30 payment. Here is what they typically require:

  • Business registration: must be a registered Portuguese business (NIF, registered with Conservatória do Registo Comercial).
  • Trading history: 6–12 months of trading history preferred. New businesses may start on prepayment or shorter credit periods (Net 7 or Net 15).
  • Credit check: carriers run a credit check via Coface, Euler Hermes or similar credit agencies. A clean credit history is required.
  • Shipping volume: credit terms are typically extended to accounts with 30+ shipments/month — below this, prepayment or card-on-file is standard.
  • Deposit: some carriers ask for a deposit (equal to 1–2 months estimated spend) from new accounts while building track record.

Managing Shipping Costs on Account

Invoice billing makes it easier to manage and reduce shipping costs because you have data on every shipment. Here is how to use your invoice data effectively:

  • Cost allocation: assign shipment costs to departments, projects or customer orders using reference fields (PO number, cost centre) when booking — these appear on your invoice for easy cost splitting.
  • Weight audits: carriers sometimes re-weigh parcels and adjust the invoiced weight post-shipment. Check your invoice against your own shipping records monthly — disputes must be raised within 30 days of invoice date.
  • Surcharge monitoring: fuel surcharges, remote area fees and residential delivery surcharges can add 15–30% to base rates. Review monthly for unexpected charges.
  • Carrier benchmarking: with multi-carrier invoices, compare cost-per-kg by carrier and route monthly — use the data to route future shipments more efficiently.
  • Annual rate review: use 12 months of invoice data to renegotiate your rate card annually. Higher actual volume than your original commitment strengthens your position.

Late Payment and Disputes

Maintaining clean payment on carrier accounts is important — late payments can result in account suspension, which disrupts your shipping operations. Here is what to expect:

  • Late payment: carriers typically send reminders at 35, 45 and 60 days. At 60+ days overdue, account suspension is common — all shipments revert to prepayment until balance is cleared.
  • Invoice disputes: if you believe a charge is incorrect (wrong weight, wrong zone, duplicate charge), raise a formal dispute with your account manager within 30 days of the invoice date. Carriers accept disputes via email with supporting evidence (your own weight/dimension records).
  • Credit limit: each account has a credit limit (e.g. €5,000/month). If your shipment value exceeds the limit mid-month, you may be asked to make a part-payment before the billing cycle ends. Monitor your running total if you have a busy shipping month.

Frequently Asked Questions

Can I get 30-day credit terms as a new business?

It is harder but possible. New businesses without trading history often start on shorter terms (Net 7 or Net 15) or prepayment for the first 3–6 months while the carrier assesses payment behaviour. Providing financial statements, a bank reference or a deposit can help secure credit terms faster. If you book through Cargosender, Cargosender's own creditworthiness covers the carrier relationship — you then have a billing relationship with Cargosender rather than the carrier directly, which may make terms easier to access as a new business.

How do I recover VAT on shipping invoices?

Shipping invoices issued in Portugal carry IVA at 23%. As a Portuguese VAT-registered business (NIF with IVA registration), you can recover this as input tax on your quarterly Declaração Periódica do IVA (IVA return). Ensure the invoice is addressed to your business name and NIF — not to an individual. Keep all carrier invoices with your accounting records for 10 years (Portuguese tax documentation requirement). If you ship internationally, some cross-border services may have zero-rated VAT — check with your accountant for the correct VAT treatment per service type.

What payment methods are accepted for carrier invoices?

Portuguese carrier invoices are typically paid by SEPA credit transfer (bank transfer from Portuguese or EU bank account using IBAN). Some carriers also accept Multibanco (MB) reference payment for smaller amounts. Credit card payment is usually only available for retail/spot bookings, not invoice billing. Ensure your accounting system is set up for SEPA transfers and that payment references match the invoice number — carriers match payments by invoice reference.

What happens if I want to dispute a charge on my shipping invoice?

Contact your account manager (for direct carrier accounts) or Cargosender support (if booked through the platform) within 30 days of the invoice date. Provide: the invoice number, the shipment tracking number, the disputed charge and your evidence (your parcel weight/dimensions, proof of delivery, photos if relevant). Carriers have formal dispute processes and typically resolve weight disputes within 5–10 business days. Do not withhold payment of an entire invoice while a partial dispute is in progress — pay the undisputed amount and dispute only the specific charge.

Can I get shipping invoices in my accounting software?

Carrier invoices are typically issued as PDF documents by email. For accounting software integration: Cargosender can provide CSV/Excel export of shipment data matching invoice line items, making it easier to import into accounting systems (Sage, QuickBooks, Primavera, SIX). Direct carrier API connections (available for high-volume accounts) can automate invoice data into your ERP. Your accountant or CFO can advise on the best format for your specific accounting system.
