How to share the public area service fees of the two property companies?

If the expenses listed in an invoice need to be shared by two or more companies, the unit that keeps the original invoice shall issue a separate invoice to the unit that should bear the expenses of other companies.

The payer of the invoice keeps the original documents and issues them to other companies that should bear the expenses. Equivalent to self-made original vouchers. The original voucher split sheet must contain the basic contents of the original voucher (voucher name, date of filling in the voucher, name of the unit or individual filling in the voucher, signature or seal of the agent, name of the unit receiving the voucher, economic business content, quantity, unit price and amount), indicate the cost sharing situation, and affix the financial seal of the unit on the split sheet.
