An invoice prepared in one application, submitted manually through another and saved in a separate folder can leave different versions and repeated checks. Contracts circulating between several signatories create similar problems. Digitalising these documents means defining the complete journey: checked data, approval, issuance or signing, confirmation and preservation of evidence.
E-invoicing and electronic signature services can become part of document and financial process digitalisation. The design addresses both the connections between applications and the person authorised to approve each operation.
PDF invoices and structured electronic invoices
A PDF provides a readable representation of a document. Romania's RO e-Factura technical workflow uses structured XML data and responses from the national system. ANAF guidance describes generation, validation, submission and download. An integration therefore needs to track the structured document and processing outcome rather than simply saving a PDF in a folder.
The business application distinguishes states such as prepared, approved, issued, submitted, accepted for processing or rejected, according to the specific provider and interface. Preparing a document is different from submitting it. Sending a technical request also needs to remain distinct from receiving its final confirmation.
Who the service is for
It suits companies generating documents in several applications, online stores, providers with recurring billing and organisations with internal approvals. A smaller team can also benefit where customer and service details are entered repeatedly or supporting records are difficult to retrieve.
The analysis identifies transaction types, the issuing entity, accounting software, authorised service access and the roles involved. Applicable tax requirements and deadlines are validated with the responsible specialist, then translated into explicit operating rules and monitoring. The project does not assume that every company follows the same document workflow.
What an invoicing integration can include
- Consistent commercial data: customer details, tax identifiers, items, units, values and checked rounding rules.
- Approvals: document review and operation confirmation by an authorised role.
- Application connections: data from a CRM, ERP or store through available, authorised interfaces.
- Validation and submission: required formats, response handling and linked identifiers.
- Monitoring: outstanding documents, validation errors and assigned corrective actions.
- Preservation: structured files, readable representations and processing evidence under the agreed policy.
Automation can prepare documents and check that required data is present. Fiscal issuance and submission are configured as separate actions with defined authority and timing. A payment or accepted quotation should not indirectly trigger an operation outside the approved procedure. The event and resulting action need an explicit, reviewable relationship.
Electronic signatures in the contract workflow
Signing begins with an approved document version, identified signatories and the signing order. The workflow covers invitations, document access, signing and result verification. At completion, the company retains the signed file and associated evidence rather than only an email notification.
The European Commission distinguishes electronic signature types and associated trust services. The project selects a level appropriate to the document and context with the person responsible for legal requirements. Pasting a signature image into a PDF does not provide the certificate-based cryptographic mechanisms used to verify integrity and signer identity.
A connection to a CRM or archive can update contract status and notify the owner. Where a document changes after being sent, the process stops the old version and establishes the procedure for the replacement. Recipients should be able to identify precisely which version they are signing.
An illustrative workflow with human approval
A service provider prepares a quotation and, following acceptance, generates a contract from approved details. An authorised person checks the parties, scope and values before sending it for signature. Completion links the signed document to the customer and project with appropriate permissions.
At the billing stage, the application prepares a document and presents the customer, tax identifier, net amount, VAT, total, currency and proposed operation to the authorised person. Approval executes only the configured action and starts outcome tracking. Errors are assigned to an owner. Before resubmission, the workflow checks identifiers and previous results to prevent duplicate documents or submissions.
Advantages and project acceptance checks
A connected workflow reduces repeated entry, makes blocked documents visible and simplifies retrieval of evidence. Operational progress can be measured through preparation time, rejections caused by incomplete records and exception resolution time. For contracts, a useful measure is the time from approval to completion by all parties.
Tests cover incorrect tax details, temporary interface unavailability, delayed responses, repeated notifications and a change of signer. We also check access expiry or revocation, preservation and export. Credentials and certificates need dedicated management, limited access and an assigned owner. Acceptance includes retrieving a completed document with its history, not only sending a new one successfully.
Frequently asked questions about invoicing and signing
Can our existing invoicing application remain?
Yes, where the provider offers a suitable interface or export. We verify supported operations, authentication, responses and usage limits before defining the integration. Existing document numbering and accounting responsibilities are included in that review.
Is emailing a PDF enough for RO e-Factura?
A PDF is a readable representation. The RO e-Factura workflow must handle the structured format and confirmations required for the particular operation. The company retains these related files in its records.
What happens when a submission receives an error?
The document remains in an identifiable state with the message and responsible owner. The procedure defines correction, revalidation and permitted resubmission after checking the previous result and identifiers.
Does every document require the same signature?
The level and service depend on the document, parties and applicable requirements. The project records the decision and checks, including who has authority to sign on behalf of the company.
Can incoming invoices also be organised?
Yes. The workflow can include authorised retrieval, supplier checks, matching against a purchase and internal approval. Receiving a document and authorising it for payment remain separate states.
How does the project start?
We inventory documents, applications and approvals, then test a representative workflow. A quotation for integrating invoicing and signing into business digitalisation separates development, provider services, migration and support.
