Invoices are part of the boring-but-important side of running digital services.
We try to make them as straightforward as possible.
An invoice tells you what you're paying for, how much you're paying, when payment is due, and who is providing the service.
This article explains how invoicing generally works across the fortheworld and development.city ecosystem.
1. When Do We Issue an Invoice?
The timing of an invoice depends on the service and the agreed payment terms.
An invoice may be issued:
Before a service begins
When an order is placed
At the beginning of a subscription period
After a service is delivered
At an agreed project milestone
On a recurring billing schedule
According to the terms of a specific customer agreement
The applicable service page, proposal, subscription, order, or agreement will determine the relevant billing arrangement.
2. What Does an Invoice Include?
Depending on the transaction, an invoice may include:
Our company information
Customer information
Invoice number
Invoice date
Service or product description
Quantity where applicable
Unit price where applicable
Subtotal
VAT or other applicable taxes
Total amount due
Currency
Payment due date
Payment instructions
Relevant payment or transaction information
For business customers, additional information may be included where required for accounting or tax purposes.
3. Who Issues the Invoice?
Services within the development.city ecosystem are operated by fortheworld OÜ, unless a particular service clearly identifies another contracting entity.
The relevant invoice should identify the legal entity responsible for the transaction.
The development.city ecosystem may contain multiple products, services, platforms, and customer-facing interfaces, but the legal entity behind the applicable transaction remains the entity identified in the relevant agreement or invoice.
4. Invoice Numbers
Each invoice may have a unique invoice number or other reference.
Please use the invoice number when contacting us about a billing question.
It helps us locate the correct transaction quickly.
For example, instead of:
"I think I was charged for something last month."
it's much easier to investigate:
"I'm asking about invoice #12345."
Tiny detail.
Huge difference.
5. Currency
The currency used for a transaction will be shown before or at the time of purchase, or in the applicable agreement.
Depending on the service and customer relationship, prices may be provided in currencies such as:
EUR
USD
GBP
Other supported currencies
The currency shown on the invoice is the currency applicable to that transaction.
If your payment provider converts the amount into another currency, the exchange rate and any conversion charges may be determined by the payment provider or your bank.
6. VAT & Taxes
VAT and other applicable taxes depend on factors such as:
Whether you are a consumer or business
Your country
Your VAT status
Where the customer is established or located
The type of service
Applicable tax rules
Whether reverse charge applies
The applicable VAT treatment should be reflected on the invoice where required.
For more information about VAT treatment, see:
VAT & EU Invoicing
7. Business Customers
If you purchase services on behalf of a business, please provide accurate business information before invoicing where required.
This may include:
Legal business name
Registered address
VAT identification number
Company registration information
Billing contact
Other information required for the transaction
For EU business customers, providing a valid VAT number can be important for determining the applicable VAT treatment.
If your business information changes, please let us know so future invoices can be issued correctly.
8. Consumers
If you purchase services as an individual consumer, your invoice and applicable tax treatment may differ from those applicable to a business customer.
Consumer rights are governed by applicable law and the terms relevant to the service you purchase.
Nothing in an invoice removes or limits mandatory consumer rights.
9. Recurring Invoices
Subscriptions and recurring services may generate invoices automatically according to the applicable billing cycle.
For example, a service may be billed:
Monthly
Quarterly
Annually
According to another agreed cycle
The applicable billing frequency should be communicated before you commit to the service.
Recurring invoices normally correspond to the service period being billed.
10. Project & Milestone Invoices
Custom projects may use milestone-based invoicing.
For example:
Project start → Development → Delivery → Final payment
The exact structure depends on the agreement.
A project invoice may therefore not follow the same schedule as a standard subscription.
If your project has milestone payments, the applicable proposal or agreement takes precedence.
11. How Do I Receive My Invoice?
Invoices may be delivered electronically through the communication or billing method associated with your service.
Depending on the service, this may include:
Email
Customer account
Billing portal
Project environment
Other electronic delivery method
Please keep your billing contact information up to date.
If you believe an invoice should have been issued but you cannot find it, contact us and we'll help locate it.
12. Can I Request a Copy?
Yes.
If you need another copy of an invoice, contact us through the appropriate billing channel and provide as much information as possible, such as:
Your name
Company name
Invoice number
Approximate invoice date
Service involved
We'll use that information to locate the relevant document.
13. What If an Invoice Contains an Error?
Mistakes happen.
If you believe an invoice contains incorrect information, contact us as soon as possible.
Examples include:
Incorrect company information
Incorrect VAT information
Incorrect amount
Duplicate invoice
Incorrect service description
Incorrect billing period
Other material billing information
Please don't simply ignore an invoice you believe is incorrect.
Tell us what looks wrong so we can investigate it.
14. Corrected Invoices
If an invoice needs to be corrected, we may issue an amended or replacement invoice or another appropriate accounting document depending on the nature of the correction and applicable accounting requirements.
Where an original invoice needs to remain part of the accounting record, the correction may be documented rather than simply deleting the original invoice.
This helps maintain a clear audit trail.
15. Payment Status
An invoice may have a status such as:
Pending
Due
Paid
Partially paid
Overdue
Cancelled
Refunded
Credited
The status reflects the payment information available to us and may take some time to update when payments are processed through external providers or bank transfers.
16. Payment References
When paying by bank transfer or another method requiring a payment reference, please use the reference provided on the invoice.
This helps us match the payment to the correct invoice.
If you accidentally use the wrong reference, contact us and provide the payment details so we can investigate.
17. Keeping Your Invoices
We recommend keeping copies of your invoices for your own accounting and record-keeping requirements.
Businesses may have legal obligations concerning how long financial records must be retained.
Your own accountant or tax adviser can advise you on the requirements applicable to your organisation.
We also retain financial records where required for legal, accounting, tax, contractual, or other legitimate purposes.
18. Privacy & Invoices
Invoices can contain personal and business information.
We therefore treat invoice information as part of the information covered by our Privacy Policy.
Depending on the transaction, an invoice may contain information such as:
Name
Address
Company information
VAT information
Email address
Service information
Payment information
Transaction references
We use this information for billing, accounting, legal, tax, contractual, and related legitimate purposes.
19. Third-Party Payment Providers
Some payments may be processed through third-party payment providers.
In those cases, the payment provider may process payment-related information according to its own terms and privacy policy.
The payment provider may also have its own requirements concerning:
Payment verification
Fraud prevention
Currency conversion
Transaction processing
Refunds
Chargebacks
The applicable payment provider's terms may therefore apply alongside our own terms.
20. Invoices & Subscriptions
An invoice confirms a billing transaction.
It does not necessarily mean that a subscription cannot be cancelled.
If you want to stop a recurring service, follow the cancellation procedure applicable to that service.
For more information, see:
Subscription & Billing Cycles
and
Refunds & Cancellations
21. Questions About an Invoice
If something on your invoice doesn't make sense, ask.
Please include the invoice number whenever possible.
We'll help explain:
What the charge relates to
Which service period it covers
How the amount was calculated
What taxes were applied
What payment is still outstanding
What you need to do next
An invoice shouldn't be a puzzle.
The Short Version
Your invoice tells you:
Who you're paying.
What you're paying for.
How much it costs.
What taxes apply.
When payment is due.
How to pay.
If something looks wrong:
Don't guess. Ask us.
We'll investigate it.
Build better. Connect smarter. Scale sustainably.
