Company Formation & Registration
Before the first EIS invoice can be transmitted, a Philippine company must clear five administrative hurdles: SEC or DTI registration, BIR TIN, VAT enrolment, LGU business permit and a corporate bank account. This cluster covers each step and shows exactly where the 4b2b ecosystem plugs in.
Registering a Corporation with the SEC
Philippine stock corporation registration via SEC eSPARC: articles of incorporation, minimum paid-up capital, by-laws filing and the path to BIR TIN and EIS enrolment.
Sole Proprietorship & DTI Registration
Registering a sole proprietorship or business name with the Department of Trade and Industry (DTI) in the Philippines: compliance obligations, VAT threshold and EIS invoicing for individual traders.
BIR Registration & TIN
Obtaining a BIR Taxpayer Identification Number (TIN) in the Philippines: the foundation for EIS enrolment, VAT registration and customs declarations — and how company data must be kept consistent.
VAT Registration
When VAT registration is mandatory in the Philippines (PHP 3 million gross sales threshold), how to register through BIR and how to issue correct 12 % tax invoices via EIS from registration day.
Business Permits — LGU / Mayor's Permit
Obtaining and renewing the Mayor's Permit (Business Permit) and barangay clearance from the local government unit (LGU) in the Philippines — and how permit data feeds into BIR filings.
Corporate Bank Account & Registered Address
Opening a corporate bank account in the Philippines, reconciling GCash and Maya receipts against open EIS invoices, and keeping registered-address data consistent across BIR and SEC.
