How to split the bill when two people do business together?

Legal subjectivity:

The issue of account sharing in partnership business is first decided according to the partnership agreement. If the partnership agreement is not stipulated or clearly stipulated, it shall be decided by all partners through consultation. If the partnership agreement stipulates that some partners shall bear losses or distribute profits, this clause is invalid.

Legal objectivity:

Article 33 of the Partnership Enterprise Law, the profit distribution and loss sharing of a partnership enterprise shall be handled in accordance with the provisions of the partnership agreement; If the partnership agreement is not stipulated or clearly stipulated, it shall be decided by the partners through consultation; If negotiation fails, the partners shall allocate and share the capital contribution in proportion to the paid-in capital; If the proportion of capital contribution cannot be determined, it shall be equally distributed and shared by the partners. The partnership agreement shall not stipulate that all profits shall be distributed to some partners or all losses shall be borne by some partners.
